This invention relates to new and useful improvements in a hat fianging and hydraulic machine .to. .produce a mellow hat. The body may be made solid (compact) by pressing the pores 5 together. The invention makes use of rubber parts for contacting the hat during the applictation of the pressure to obtain the mellow qual Furthermore'it is proposed to save one operation by treating the brim and crown simultaneously. The hat brim need not be curled, therefore the edge will not be cracked.

v The invention has for an object the constructionof amachine as mentioned which is adapted .to give a better flanged hat, to give a brim as mellow or firm as desired, and to give uniform pressure on the entire surface of the brim for uniformly shaping and finishing it. 7

More-specifically, the invention proposes the construction of a machine as mentioned which is characterized by a hat block= top section mounted on. a, pressure carriage and cooperative with a bottom section, and comprising-a hollow body for H hydraulic -substance-,- and a conformable dia- 2 phragm in the bottom of said hollow body and engageable on the flange or brim of a hat on a block .bottom section, ,for transferring pressure thereto.

I For further comprehension of the invention, andof the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set '36 forth. I

The hat flanging and hydraulic machine, acm cording to this invention, comprises a frame consisting of a top member I0 supported by a pair of side members II, to a base member l2. A transverse brace I3 is mountedbetween intermediate points of the side members H. An annular hat block bottom section I4 is movably supported on said frame and is adapted to be positioned in a pressure receiving position. A pressure carriage i5 is mounted on said frame above saidpressure receiving position. A hat block top section i6 is mounted upon the pressure carriagev and is.co-.

operative with the bottom section and comprises a hollow body l6 for hydraulic substance and a conformable diaphragm I! on the bottom. of i said hollow body and engageable on the flange or brim of a hat on said bottom section for transferring pressure thereto. The center of the diaphragm I! is secured to the center of the hollow body by a bolt 16 or the like.

The pressure carriage includes a pair l5 which are slidably mounted on the side members l I. These sleeves arefixedly mounted upon the sides of the hollow body Ili At spaced poof sleeves sitions on the body l6 there are pairsof lugs 18 to which links l9 pivotally'connect. These links I9 pivotally connect with. links 20 which are pivotally-supported at their'top endsupon the bot-v tom face of the frame head member l0. A lever 2| projects from one of the links'l9 by which said link may bepivoted to align the links l9 and 20 and so force the pressure carriage downwards. The partsare arranged so that when these links are nearly aligned in a Vertical plane Y the hot block sections are engaging each-other.

It is thus possible to manually apply a great pressure between the block sections. The carriage I5 is counter-balanced by cables 23 which extend upward over guides 24 and'then extend down; ward over guides 24 tending ends of these cables support a counter weight 26. I

The bottom block section l4 is supported upon an undercarriage 2'! whichhas several casters 28 engaging a track 29 extended outwards to .6116 front of the machine. The undercarriage The latter downward ex- N 21 is provided with a handle by which it may be gripped and moved outwards. The undercarriage 21 is in the form of an annular hollow body in which a heater 3| (electric or gas) is mounted. Gas pipes 3P or steam pipe 3| may also be connected with the interior of the undercarriage by which it may be heated. This heater 3| is connected with an electric line 32 which may be connected with a source of electricity. The block bottom section I4 also is of annular shape and has an inside wall W into which a hat body may engage. This annular member has a curved top and side wall I l upon which the brim or flange of the hat may rest.

The block member section has an annular ring 34 which clamps down on annular canvas or other gasket 35 adjacent which the diaphragm" I! is positioned. The diaphragm l'l extends across the bottom of the hollow body is and is secured in position by bolts 35 which engage through a flange on the hollow body 16 and through the annular member 34. The "diaphragm I! is conformable with the curved shape of the side W of the bottom block section.

The hollow body l6 may be filled with hydraulic substance through a funnel 38 which is mounted on the top of the body. A valve 39 controls the discharge of hydraulic substance from the funnel 38. A pressure valve All is mounted on the hollow body 46' and may be connected with or shut oif from the hollow body by a control valve H.

The operation of. the device is as follows:

The valve 39 is opened and the compartment within the hollow body I0 is filled with 'a hydraulic substance. The bottom block section It is then drawn out by pulling on the handle 30 so that under-carriage moves outwards. A hat is then dropped into the bottom block section as indicated by the dot and dash lines A9, in Fig. 4. The bottom block section is then moved inwards to its pressure receiving position as shown in Fig. 4. Then the lever 2! is pivoted downwards to pivot the links [9 and 20 and force the back pressure downwards.

The diaphragm I! will strike the flange or brim of the hat '49 and will conform with the shape of the hat. The hydraulic substance within the compartment 16* will flow to permit the diaphragm I! to conform with the block bottom section, and after the conformation the hydraulic substance will be incompressible so that it is possible to transfer a large pressure against the brim of the hat. The pressure may be watched by watching the gauge 40.

In Figs. '7-12 inclusive, another embodiment of the invention has been disclosed which is very similar to the previous form, distinguishing merely in details of the different parts. According to this form of the invention there is a machine frame which includes the side members It. On these side members there is a pressure carriage [5 which is slidably mounted. This pressure carriage is controlled by a pressure sys tem which includes the links 19' and the manually operable handles or lever -2-l. An annular hat block bottom section 14' is mounted on an under-carriage '21 which is slidable on tracks 29' forming -a portion of the bottom member i=2 of. the frame of the machine.

The block top section has a hollow body l6 across the bottom side of which there is a diaphragm IT. This diaphragm is shaped to have a projecting central portion I! which is adapted to engage into the crown of the hat 49' mounted on the bottom section i4 so that hydraulic pressure may also be extended to the crown of the hat as well as the brim. A hydraulic substance supply funnel 38' is connected with the hollow body I6 A pressure gauge 40' is mounted upon the hollow body IB An air supply pipe 49 with a control valve 40 connects with the gauge ill to which there is also connected an exhaust line 40 with a control valve 40 A pipe 6G connects the gauge 40' with the hollow body it. The funnel 38" is controlled by a valve 39 and supplies hydraulic substance to the body it. The diaphragm I1 is held in posi tion by an annular canvas element 35' and an annular member 34.

The under-carriage 29 has a large interior compartment 50 with several openings Si in the walls thereof. Through these openings air is supplied for gas burners 3l on the inner ends of gas pipes SI The bottom block section I4 is formed of two members. There is a bottom member M adapted to extend completely around and encase the crown of a hat. The top member M is aligned with the bottom member W by notches 53 and corresponding protruding members 54 on the parts which are held connected by several screws 52. Furthermore a projection 55 from the bottom member l4 engages a recess 56 in the top member N A sheet rubber covering member hi extends over the outer surface of the top member N and is held in position by an annular projecting rib 56 on the covering member engaging in a groove in the side of the top member M Projections 57 from the covering member M are engageable in receiving recesses E8 in the bottom member for assisting in holding the members together and for holding the covering member 14.

In other respects this form of the invention is identical to the previous form and similar parts and the operation may be readily understood by an inspection of the parts and a consideration of the prior form. The main distinguishing feature of this modified form of the invention is that the crown as well as the brim of a hat will be treated with pressure.
